Ethernet is well known for its ease of use and cost effectiveness and is rapidly gaining acceptance in Carrier networks. While traditional SONET/SDH based technology in carrier networks is replaced by Ethernet, suitable services OAM support (ITU-Y 1731 and IEEE 802.1ag) is need to be supported in the network. Also, in the core of the network, MPLS being the predominant technology is being positioned as the basis for Provider Backbone Transport (PBT) technology, in addition to IEEE standards relating to Provider Bridges and Provider Backbone Bridges. ATTEST test solutions cover the full breadth of Carrier Ethernet network technologies:
Veryx ATTEST CATS Service OAM (Y.1731) is a feature rich comprehensive automated test suite for conformance verification of Y.1731 in Fast Ethernet and Carrier Ethernet devices.
ITU-T Y.1731 specifies user plane OAM mechanisms. OAM provides tools for carriers to manage their end-to-end services. Y.1731 defines Maintenance Entity Group and Maintenance End Points to monitor a service. Fault management and Performance Monitoring are done through the various functions specified by Y.1731.
Y.1731 OAM functions are applicable to both point-to-point and multipoint situations.
